Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design it being understood that the tread pattern is repeated uniformly throughout the circumference thereof;

FIG. 2 is a front elevational view thereof on a reduced scale, it being understood that the opposite side is the same as that shown; and,

FIG. 3 is a side elevational view thereof.

The continuous circle between the outer end of the tire tread and the sidewall shown in FIGS. 2 and 3 of the drawing is for the purpose of defining the peripheral boundary of the tire tread and forms no part of the claimed design. In addition the broken line showing of the sidewall in FIGS. 2 and 3 of the drawing is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
